Answer:
$8,430.23
Explanation:
From the statement of the problem:
• The principal amount = $8,000
,
• Interest Rate = 5%
,
• Compounding Period = 12 (Monthly)
The compound interest formula is given as:

Using the compound period formula, we first, calculate the amount in her account at the end of 1 year.

This means that the interest she made during the first year is:

Next, calculate the amount in her account at the end of the second year.

Since she paid back all the interest she made during the first year, the amount Diana was left with is:

Diana was left with $8,430.23.
You should first add -10 and 24. Then you should subtract 7x and 2x. All you have to do is to find the like terms ( 7x and 2x because they both have x’s, and -10 and 24 because they don’t have x’s). So your answer would be 14+5x. If you have any questions please reply.
